Abstract
A chitin-containing polyester filament and a preparation method of the chitin-containing polyester filament are provided. The method includes preparing a modified chitin; preparing a chitin-containing functional modifier based on the modified chitin; preparing polyester (PET) functional particles based on the chitin-containing functional modifier and PET pellets; preparing a mixed spinning solution based on the polyester functional particles, where a weight percentage of the polyester functional particles is in a range of approximately 2%-4% based on a total weight of the mixed spinning solution; and performing a spinning molding of the mixed spinning solution to form the chitin-containing polyester filament.
